What is the author's style in Shooting an Elephant by George Orwell?

The narrative, while broken up by the narrator's reflections on the events he is recalling, is essentially straightforward and makes use of two motifs, inevitability and augmentation. As soon as the narrator receives the telephone report of the rogue elephant, it becomes inevitable that he will have to kill the animal; merely going out to see what is happening insures this, as does the discovery of the trampled Burmese man, and the narrator's sending for the elephant gun and cartridges. The increasingly agitated crowd (augmentation) also militates against sparing the animal. The increasing size and unanimity of the crowd thus also functions as part of the story, the mob itself becoming something ever more enormous and dangerous, like a rogue elephant, whose danger the narrator avert only through offering it what it wants, namely the death of the creature (and the subsequent boon of its flesh). The story exhibits a certain rhythm, already remarked, that of meditation and action; it starts with reflection, tells part of the story, reflects further, offers its climax, and then ends with a final reflection.
